1986, the Chernobyl nuclear power plant meltdown released Cesium-137 into the urrounding area, making it radioactive for many years to come. Cesium-137 decays at a rate of A(t) = Ae-0.0231t, where A(t) represents the amount of Cesium-137 left after a given time (in kilograms), A, represents the initial amount of Cesium-137 (in kilograms), and t represents the number of years. If the meltdown released 30 kilograms, how many years will it take for the amount of Cesium-137 to get to a safe amount of only 0.25 kilograms in the area?
